Pooping Problems....TMI

So I had my 2nd on the 24th and had a successful VBAC. I pushed for 4.5 hours and didnt tear. Ive had a great recovery so far, so much easier than my c section but I'm having issues going #2. The first PP poop literally fell put of me, I couldnt stop it or slow it down, I was running to the toilet, good thing I had a pad on. I didn't go again for several days even though I felt like I constantly had to go. When I did go it was super soft and a ton, like I didnt know I could even have that much in my body. I havent been able to go for days and have been trying but its like my muscles dont know how to push there anymore. I feel like I cant stop it when it starts and I can't start it on my own, it just sort of happens. Is this common with a vaginal birth? When will it get better?
